Cupro Nickel Density & Price per KG in India
With reference to Cupro Nickel Density & Price per KG in India, the Density of Cupro Nickel is 0.323 lb/in³ (8.94 g/cc). Cupro Nickel price per kg in India is Rs 560. That means that the price of Cupro Nickel per kg would be roughly around 6.30 Pounds. Of course, this would not mean that Cupro Nickel would be available at this very same price in other parts of the globe such as USA, Singapore, China, Japan, Europe, UK, etc. For instance, the price of Cupro Nickel is roughly 5% higher in India, than it is in China. Yet, you could buy Cupro Nickel in India, for 35% lesser than you could buy it in America. Also, the price of Cupro Nickel is always fluctuating.

Titanium Hastelloy C Inconel 625 |
Titanium will pit at temperatures above 120°C. Inconel 625 after 2-3 years shows signs of incipient pitting in some tests in quiet seawater |

|
Crevices cannot be tolerated in designs (But usable in above the waterline marine applications)
|
Nickel | Many deep pits develop.Cathodic protection from less noble alloys required |
| Grade 304 Stainless Steel | Many deep pits develop.Cathodic protection from steel may not be fully effective | |
| Precipitation Hardening Grades of Stainless Steel | Many deep pits develop.Cathodic protection with zinc or aluminium may induce cracking from hydrogen | |
|
Severe crevice corrosion limits usefulness
|
Grade 303 Stainless Steel | Severe pitting.Cathodic protection may not be effective. |
| Series 400 (ferritic or martensitic) Stainless Steel | Severe pitting.Cathodic protection with zinc or aluminium may induce cracking from hydrogen. | |
|
Useful although cathodic protection required on critical surfaces
|
Monel 400 (nickel-copper alloy) | Pits tend to be self-limiting in depth at about 1-6 mm.No protection required for heavy sections.Cathodic protection from steel or copper base alloys will prevent pitting on O Ring, valve seats, and similar critical surfaces. |
| CN7M (Alloy 20)Incoloy 825 | Occasional deep pits will develop.Protection not normally required for all alloy 20 pumps.Cathodic protection from less noble alloys may be necessary for O Ring and similar critical surfaces. | |
| Grade 316 Stainless Steel | Cathodic protection from zinc, aluminium, or steel is required except when part is frequently removed from seawater and thoroughly cleaned |
